What is an Attribute?

An attribute is a characteristic of a particular component in the 3D world like an areas or a construction. An attribute is always a number and can have a positive or a negative value.

Attributes in relation to the Tygron Engine

Attributes contain information about a particular component which can be used in Excel calculations. The value of an attributed can be changed as a result of an Excel calculation or as the result of an event. Some of the attributes and their value at the start of the project are added by default. It is also possible to add or adjust attrubites and the value manually. In addition, there is also the possibility to import attributes as part of importing GeoJSON files. The Engine's component where attributes are applied to are: neighborhoods, areas, constructions and zones.

The attribute is always described as number value. When the attribute is not given as a number the outcome of a calculation will be zero. But it is also possible that the legit outcome of a calculation is zero. Therefor, when the outcome is zero it can be wise to check the spreadsheet for errors.

When you want to make use of an attribute in an Excel indicator you need to specify in the spreadsheet if the attribute is included int the calculation or not. This is done by the ACTIVE attribute. For the ACTIVE attribute the input is always 1 for active and 0 for not active.
